Answer:
C. population in a cartogram
Explanation:
The map that is depicted shows us population in a cartogram. The population density on this map is represented with concentric circles, smaller and larger ones, depending on the are that is inhabited, and more dense and less dense, depending on where there is higher concentration of population.
From the map we can see that some parts of the world are sparsely populated, like Oceania, the northern parts of Asia, Europe and North America, as well as Sahara in Africa. We see this because on those places the concentric circles are either very small and isolated, or are totally lacking, meaning that the population is very small.
On the other hand, we can see that some parts of the world are actually densely populated, like East, South, and Southeast Asia, East and West Africa, most of Europe, parts of the United States and the central-east coast of South America. This can be seen because there are larger concentric circles, as well as the circles being much denser, meaning that the population is very large.
